Astronomy Tue, 06 Dec 2016 06:07:52 ESTnews400226865What do aliens look like? The clue is in evolutionSpeculating about what aliens look like has kept children, film producers and scientists amused for decades. If they exist, will extra terrestrials turn out to look similar to us, or might they take a form beyond our wildest imaginings? The answer to this question really depends on how we think evolution works at the deepest level.http://phys.org/news/2016-08-aliens-clue-evolution.html

According to a new study, the smallest of the newly detected alien worlds is about 38 times more massive than the Earth and has a radius nearly nine times greater than the radius of our planet. The discovery is reported in a paper published on Apr. 14 on arXiv.org.http://phys.org/news/2016-04-astronomers-giant-exoplanets.html

This visualization, created by graphic artist and writer Martin Vargic from Slovakia, is based on the estimated radius and temperature of the planets, however other factors, such as density, age or stellar metallicity were also taken into consideration. All the various known classes of exoplanets are shown on the graphic, such as super-Earths, hot Jupiters, hot Neptunes, water worlds, gas dwarfs or superdense diamond planets.http://phys.org/news/2015-11-visualization-incredible-variety-extraterrestrial-worlds.html

But within the next generation, it should become possible to detect signs of life on planets orbiting distant stars. If we find alien life, new questions will arise. For example, did that life arise spontaneously? Or could it have spread from elsewhere? If life crossed the vast gulf of interstellar space long ago, how would we tell?http://phys.org/news/2015-08-interstellar-seeds-oases-life.html

Most stars, including our Sun, are born in small, benign groups that quickly fall apart. Others form in huge, dense swarms that survive for billions of years as stellar clusters. Within such rich and dense clusters, stars jostle for room with thousands of neighbors while strong radiation and harsh stellar winds scour interstellar space, stripping planet-forming materials from nearby stars.http://phys.org/news/2013-06-transiting-planets-star-cluster.html

The two most prolific techniques for finding exoplanets are radial velocity (looking for wobbling stars) and transits (looking for dimming stars). A team at Tel Aviv University and the Harvard-Smithsonian Center for Astrophysics (CfA) has just discovered an exoplanet using a new method that relies on Einstein's special theory of relativity.http://phys.org/news/2013-05-method-planets-scores-discovery.html
